Ninety-four patients with patent ductus arteriosus, whose ages ranged from 28 weeks gestation to 8 years, were assessed by suprasternal cross-sectional echocardiography. A further group of 37 cases without a patent ductus arteriosus were assessed by the same technique. The appearances of the ductus via this approach varied according to the ventriculoarterial connections. Reliable assessment of ...

The ductus arteriosus is an arterial vessel that shunts blood flow away from the lungs during fetal life, but normally occludes after birth to establish the adult circulation pattern. Failure of the ductus arteriosus to close after birth is termed patent ductus arteriosus and is one of the most common congenital heart defects. Mice with smooth muscle cell-specific deletion of Jag1, which encode...

Duration of ductal shunting in healthy preterm infants: an echocardiographic color flow Doppler study. Early echocardiographic prediction of symptomatic patent ductus arteriosus in preterm infants undergoing mechanical ventilation. Re-evaluation of the left atrial to aortic root ratio as a marker of patent ductus arteriosus. Selective head cooling with mild systemic hypothermia after neonatal e...

An 80-year-old man with Ebstein's anomaly and ductus arteriosus aneurysm is reported. He was admitted with bradycardiac atrial fibrillation and right ventricular failure. For the control of brady-arrhythmia, a permanent pacemaker was implanted. Two-dimensional echocardiogram revealed distal displacement of the septal tricuspid valve. Aortography and computed tomography showed ductus arteriosus ...

Purpose: To review the results of ligation of patent ductus arteriosus in premature babies in an intensive care unit. Method: Retrospective review of premature babies who underwent ligation of patent ductus arteriosus in the intensive care unit, Grantham Hospital, during the period from January, 1999 to December, 2002. Results are compared with those who underwent ligation of patent ductus arte...

A seven-week-old infant with aortic origin of the right pulmonary artery and patent ductus arteriosus is reported. During preoperative studies, a balloon catheter was used to occlude the ductus arteriosus in order to define the status of the pulmonary vascular bed. Corrective operation was performed by anastomosis of the anomalous right pulmonary artery to the main pulmonary trunk and ligation ...

BACKGROUND Ibuprofen is used for treatment and prevention of patent ductus arteriosus in low-birthweight infants. Its effects on regional circulations differ from those of indometacin. Because prophylactic indometacin reduces the frequency of severe intraventricular haemorrhage and patent ductus arteriosus, we aimed to study the efficacy of early ibuprofen in reducing these outcomes in a double...

The clinical and physiological characteristics of the uncomplicated patent ductus arteriosus in the adult have been well-defined and understood for many years. A typical continuous murmur usually develops early in life; the electrocardiogram is usually normal or shows a left axis deviation; and heart fluoroscopy ordinarily shows only mild to moderate left ventricular enlargement, vigorous aorti...

Interrupted aortic arch is a rare congenital malformation of the aortic arch defined as a loss of luminal continuity between the ascending and descending portions of the aorta. In a simple interrupted aortic arch, only a ventricular septal defect and patent ductus arteriosus are observed. We present a rare complex form of type A interrupted aorta with an aortopulmonary window, an atrial septal ...

Despite the revolutionary changes that occurred in percutaneous Patent Ductus Arteriosus (PDA) closure, classical angiographic Krichenko classification of PDA remained unchanged and its implications on ductal closure has not been frequently studied.
